About Pollen in Eastleigh

Eastleigh’s allergy season commences March-April with dominant Birch pollen, sourced from Fleming Park and urban street trees; Oak follows April-May, prevalent around Lakeside Country Park and wider local woodlands. Grass pollen peaks May-July, originating from extensive meadows within Itchen Valley Country Park and along River Itchen riverbanks.

Eastleigh’s valley topography, particularly the Itchen corridor, influences pollen trapping and dispersal; post-rain humidity locally amplifies concentrations. Autumn brings increased mould spores from October, deriving from damp leaf litter in Derby Road Park and shaded, decomposing vegetation areas, persisting through mild, wet periods.

The pollen count in Eastleigh today is moderate, driven mainly by Grass (mixed).
